CSIT Test Naming
================
Background
----------
CSIT |release| introduced a common structured naming convention for all
performance and functional tests. This change was driven by substantially
growing number and type of CSIT test cases. Firstly, the original practice did
not always follow any strict naming convention. Secondly test names did not
always clearly capture tested packet encapsulations, and the actual type or
content of the tests. Thirdly HW configurations in terms of NICs, ports and
their locality were not captured either. These were but few reasons that drove
the decision to change and define a new more complete and stricter test naming
convention. And to apply it to all existing and new test suites and test
cases.
The new naming should be intuitive for majority of the tests. Complete
description of the newly adopted CSIT test naming convention is provided on
`CSIT test naming page <https://wiki.fd.io/view/CSIT/csit-test-naming>`_. Here
few illustrative examples of the new naming usage for test suites across CSIT
performance, functional and HoneyComb management test areas.
Naming Convention
-----------------
The CSIT approach is to use tree naming convention and to encode following
testing information into test suite and test case names:
1. packet network port configuration
* port type, physical or virtual;
* number of ports;
* NIC model, if applicable;
* port-NIC locality, if applicable;
2. packet encapsulations;
3. VPP packet processing
* packet forwarding mode;
* packet processing function(s);
4. packet forwarding path
* if present, network functions (processes, containers, VMs) and their
topology within the computer;
5. main measured variable, type of test.
Proposed convention is to encode ports and NICs on the left (underlay),
followed by outer-most frame header, then other stacked headers up to the
header processed by vSwitch-VPP, then VPP forwarding function, then encap on
vhost interface, number of vhost interfaces, number of VMs. If chained VMs
present, they get added on the right. Test topology is expected to be
symmetric, in other words packets enter and leave SUT through ports specified
on the left of the test name. Here some examples to illustrate the convention
followed by the complete legend, and tables mapping the new test filenames to
old ones.
Naming Examples
---------------
CSIT test suite naming examples (filename.robot) for common tested VPP
topologies:
1. **Physical port to physical port - a.k.a. NIC-to-NIC, Phy-to-Phy, P2P**
* *PortNICConfig-WireEncapsulation-PacketForwardingFunction-
PacketProcessingFunction1-...-PacketProcessingFunctionN-TestType*
* *10ge2p1x520-dot1q-l2bdbasemaclrn-ndrdisc.robot* => 2 ports of 10GE on Intel
x520 NIC, dot1q tagged Ethernet, L2 bridge-domain baseline switching with
MAC learning, NDR throughput discovery.
* *10ge2p1x520-ethip4vxlan-l2bdbasemaclrn-ndrchk.robot* => 2 ports of 10GE on
Intel x520 NIC, IPv4 VXLAN Ethernet, L2 bridge-domain baseline switching
with MAC learning, NDR throughput discovery.
* *10ge2p1x520-ethip4-ip4base-ndrdisc.robot* => 2 ports of 10GE on Intel x520

Intel x520 NIC, IPv4 baseline routed forwarding, ingress Access Control
Lists baseline matching on destination, NDR throughput discovery.
* *40ge2p1vic1385-ethip4-ip4base-ndrdisc.robot* => 2 ports of 40GE on Cisco
vic1385 NIC, IPv4 baseline routed forwarding, NDR throughput discovery.
* *eth2p-ethip4-ip4base-func.robot* => 2 ports of Ethernet, IPv4 baseline
routed forwarding, functional tests.
2. **Physical port to VM (or VM chain) to physical port - a.k.a. NIC2VM2NIC,
P2V2P, NIC2VMchain2NIC, P2V2V2P**
* *PortNICConfig-WireEncapsulation-PacketForwardingFunction-
PacketProcessingFunction1-...-PacketProcessingFunctionN-VirtEncapsulation-
VirtPortConfig-VMconfig-TestType*
* *10ge2p1x520-dot1q-l2bdbasemaclrn-eth-2vhost-1vm-ndrdisc.robot* => 2 ports

to/from two vhost interfaces and one VM, NDR throughput discovery.
* *10ge2p1x520-ethip4vxlan-l2bdbasemaclrn-eth-2vhost-1vm-ndrdisc.robot* => 2

switching to/from two vhost interfaces and one VM, NDR throughput discovery.
* *10ge2p1x520-ethip4vxlan-l2bdbasemaclrn-eth-4vhost-2vm-ndrdisc.robot* => 2

3. **API CRUD tests - Create (Write), Read (Retrieve), Update (Modify), Delete
(Destroy) operations for configuration and operational data**
* *ManagementTestKeyword-ManagementOperation-ManagedFunction1-...-
ManagedFunctionN-ManagementAPI1-ManagementAPIN-TestType*
* *mgmt-cfg-lisp-apivat-func* => configuration of LISP with VAT API calls,
functional tests.

sub-interface events with HoneyComb NetConf Notifications, functional tests.
